I think you mean grazer, someone who eats a little, but often. That's what the medical profession told me to be, to control my Type II diabetes. But from what I've experienced, as wee as what I've learned from Dr. Jason Fung, Dr. Peter Attia, and others, this is the exact opposite of what you should do. Allowing your body to have a significant period of time (16 or so hours in my case) lets the body processes that are supposed to occur happen. Grazing stops them. I'm not sure how any of this would affect temperature, but my A1c dropped from 5.9-6.2 to 5.2 after just a few months of IF. I highly recommend it. Not so much for weight loss, that's more an effect of LCHF, but as a way to allow your body to complete it's natural cycles, which should overall improve your health.
